Su Xinyuan hung upside down shirtless, one fist on the ground, sweat slowly slid down between the lines of his strong muscles, and his hair was soaked, but he still had his eyes closed and motionless, even though he had been in this position for two hours.

Yang Yanshi, who was sitting on the side and drinking tea, showed a relieved smile.

He had never seen someone with such a high level of martial arts talent, and in just over a week, he had already mastered the first five volumes of the Jiuyang Heart Method, such a speed was simply unbelievable! The most rare thing is that this child is still so hardworking, not arrogant or impatient, and never arrogant.

"Get up, it's almost time." Yang Yan put down the teacup and commanded.

Su Xinyuan made a push on his arm, flipped his whole person in the air, and stood on the ground with his feet.

"Thank you, senior." He took a dry towel from Yang Yan's hand and wiped the sweat all over his body.

"How does it feel?" Yang Yan asked.

"My arm is numb, and I can't bear it." Su Xinyuan replied truthfully.

"That's right, I mainly want you to experience the feeling when you perform the Jiuyang boxing method, the Jiuyang boxing method is a powerful internal force poured into the arm to perform the exercises, if the arm does not have a certain ability to resist pressure, not only the power of the boxing method will be greatly reduced, but it is also likely to cause harm to the body in the long run."

"And...... Although Su Gongzi has a very good foundation of internal force, and the speed of internal force cultivation is also staggering, but your external physical fitness does not seem to be able to match the powerful internal force in your body......" Yang Yan said with some doubts.

Su Xinyuan sighed in his heart, this master is really a master, and he can see the problem at a glance.

He also knew very well in his heart that the strength of his body was indeed his own shortcoming, otherwise he would not have felt that his body was very strained every time he temporarily opened the soul system of the excellent level, and often after performing some powerful exercises, he felt that his whole body was emptied.

"Senior, is there any training method that can improve physical strength?" Su Xinyuan asked.

"A martial artist's physical qualities include speed, reflexes, resistance, and strength, which cannot be achieved overnight, but need to be accumulated over a long period of time......," Yang Yan's words suddenly changed, "I do know a shortcut, but how far you can go depends on your own creation!" ”

"What shortcut? Seniors, please speak! Su Xinyuan couldn't wait to ask.

"The Way of Dan Yuan!" Yang Yanshi said.

……

Su Xinyuan returned to the villa, holding a box of pills in his hand.

Yang Yan told him that it was not easy to quickly strengthen the strength of his body, and that the fastest results were the technical means of the B.C. or the Black Wing Society, and that the traditional method was to use pills to assist him.

But the pill is only an auxiliary role, treating the symptoms but not the root cause, if you want to really strengthen the quality of the body, you still have to go through a lot of training.

"Huh? What about Tang Xin? Su Xinyuan looked at Lixiang and Vanilla, who were watching TV in the hall, and asked suspiciously. Usually, Tang Xin is inseparable from vanilla, so now she suddenly disappeared, which made Su Xinyuan feel very strange.

"Sister Tang Xin is practicing behind the house." Vanilla said.

Su Xinyuan nodded, and then walked to the back of the villa.

He saw Tang Xin holding a branch more than two meters long, speeding on the grass, the originally soft and ordinary branch, at this time in her hand, it was like an indestructible spear, not only leaving a gust of wind howling in mid-air, but also rolling up a lot of grass clippings on the ground, falling green.

This is exactly the marksmanship of the Seven Star Mantis Fist that she is best at!

Tang Xin was already fully engaged, and he didn't even know anything about Su Xinyuan standing aside to observe.

It wasn't until he finally accepted the trick and wiped the beads of sweat on his forehead with his hand that he finally discovered Su Xinyuan's existence.

"Senior brother, why are you here?" Tang Xin looked a little surprised.

"Little junior sister, you seem to have been working hard lately!" Su Xinyuan stepped forward and said with a smile.

Tang Xin's face was slightly red, and he said a little shyly: "That's also influenced by you, senior brother...... I know that I am far inferior to my senior brother in terms of internal skills, and I am not as good as Sister Lixiang in terms of external skills, so I can only practice hard, and the stupid bird flies first. ”

"Little junior sister, you're not a stupid bird! It is said that there is a specialization in the art industry! Although my internal strength is above you, in terms of external physical strength, I, a big man, are far inferior to you! Su Xinyuan wasn't touting Tang Xin, he knew very well that if he just talked about speed, strength, reaction, and control of strength, he was indeed inferior to Tang Xin.

Tang Xin also saw that Su Xinyuan was a little abnormal, so he asked, "Senior brother, why did you suddenly talk about this today?" Did you encounter any difficulties in your cultivation? ”

Su Xinyuan nodded and said, "It is said that there must be my teacher in the threesome, it seems that I am going to ask you and Lixiang for advice today." ”

After that, Su Xinyuan dialed Lu Yun's phone, and then all of them went to the indoor stadium of the academy.

Su Xinyuan and Tang Xin had already been to this venue during the martial arts assessment of Class A of the academy last time, but this time, except for Lu Yun and a few students in white practice uniforms who were busy, the huge venue seemed empty.

On the contrary, it was the first time for Lixiang and Vanilla to come here, and they were full of curiosity about the various strange instruments placed in the middle of the venue, and they couldn't help but look around.

This is the first step of Su Xinyuan's physical strength enhancement plan, he wants to clearly understand the true level of his physical strength, and the reason why he brought Tang Xin and Lixiang is to hope to have a reference.

"Mr. Su, I have prepared everything according to your instructions." Lu Yun stepped forward and said.

"Xiao Lu, thank you, you have worked hard." Su Xinyuan said gratefully.

"So first of all, let's ask the three of you to take a strength test first, and I will record all the data for analysis." Lu Yun said with a pen and paper in his hand.

Su Xinyuan nodded, and then said to Tang Xin: "Little junior sister, you go first, don't deliberately retract your strength, you must use all your strength to show your true strength strength." ”

Tang Xin nodded, walked to the dynamometer, and showed his strength without reservation.

"13,150 pounds!"

Lu Yun recorded this number in surprise.

It was Lixiang's turn, she slowly walked to the dynamometer and threw a punch upwards quickly, and the entire machine weighing dozens of tons and deeply embedded in the ground was trembling slightly.

"21,800 pounds!"

Lu Yun looked at Lixiang in disbelief, and it took a long time to come back to his senses and record this incredible number in his notebook. And the ordinary students around him were so shocked that their jaws almost fell to the ground.

Although Su Xinyuan knew that Lixiang had been strengthened by B.C.'s strength, he was secretly surprised that she had hit this amazing number with one punch.

Finally it was Su Xinyuan's turn to play, he walked to the force tester, gritted his teeth, and swung his fist on the sensor with all his strength, and the numbers on the display began to soar rapidly, but in the end it only stayed at "4120 pounds".

4120 lbs! This is already an astronomical amount for ordinary people, more than twice the 1,800-pound limit punch power of the famous American boxing champion!

But for martial arts practitioners with a little skill, this may only be a passing grade, and it can't match the deep internal force in Su Xinyuan's body.

Of course, Su Xinyuan's punch did not use the slightest internal force, and the internal force has an amplifying effect on the strength of the body, which will increase the strength of the body exponentially. If he used his internal strength, the power of this punch might easily surpass Reika's "21,800 pounds", but that would have lost the original purpose of the trip.

He just wanted to understand the simple power of his body.

Lu Yun recorded this number with some embarrassment, and then immediately carried out the next speed test.

In the test of 100-meter displacement, Tang Xin and Lixiang were comparable, both were completed in nearly five seconds, and Tang Xin was slightly better than Lixiang.

Speed is Tang Xin's natural advantage, the world's martial arts, only fast is not broken, and the Seven Star Mantis Boxing is the essence of "fast" to the extreme. However, because Reika has undergone B.C.'s enhanced transformation, the gap between the two of them is not obvious.

As for Su Xinyuan, he still took 8 minutes and seconds to move the 100-meter displacement without the help of internal force, which is on par with the world's top 100-meter sprinters.

Although it seems that there is only a few seconds of difference, it is very likely that these few seconds will affect the final battle situation in actual combat.

The last thing to do is the body's reflexes, and in the transparent square glass room, several high-speed cameras are set up and connected to the computer next to it.

Within a minute, the top of the four-square-meter glass room will be sprinkled with a steady stream of fingernail-sized pieces of paper, a total of 1,000,100 pieces of paper in red and pink at a 1,000:1 ratio, and the subject will need to get as many pieces of pink paper as possible.

The color difference between red and pink is not much, and the massive amount of paper is very high for the reaction, discrimination and judgment of the testee.

In the end, Tang Xin got 55 pieces of pink paper from more than one million pieces of paper flying in the sky, with a completion rate of 55%, while Lixiang got 88 pieces of paper amazingly, with a completion rate of 88%.

As for Su Xinyuan, he only got 21 cards, and the completion rate was only 21%.

After the three tests, in addition to the speed, Li Xiang, who has been strengthened by B.C. modern technology, is obviously better than the traditional martial artist Tang Xin, which can be called a perfect example of external physical fitness, as for Su Xinyuan, who has always only relied on the system, attaches importance to the accumulation of internal force and ignores the strengthening of external physical strength, there is no doubt that all three are the bottom results.

These three tests made Su Xinyuan completely recognize the status quo, and a cruel reality was placed in front of him - strong inside and weak outside.

If he continued to use this body to drive a strong internal force, he could faintly see the final consequences, just like using an ordinary Browning pistol to forcibly fire a specially made enhanced bullet, which might have been able to show good power at first, but in the long run, the ordinary Browning pistol finally collapsed one day.

In order not to let his body become a drag and eventually be eaten by the powerful internal force in his body, Su Xinyuan has decided to strengthen his body strength at all costs.
